Problems solved by technology

[0003] However, due to the low strength of copper and copper alloys, they are prone to breakage during use. In the prior art, while increasing the strength of copper-based materials through deformation or solution-aging, the problem of electrical conductivity decline is often ignored. Therefore, the present invention provides a high-strength and high-conductivity copper-based material and a preparation method thereof to obtain a copper-based material with good strength and electrical conductivity

Abstract

The invention discloses a high-strength and high-conductivity copper-based material and a preparation method thereof. The high-strength and high-conductivity copper-based material comprises bronze and nanoscale additives, and the nanoscale additives comprise carbon nanotubes and nanoscale particle reinforced phases; the nanoscale particle reinforced phases comprise one or more of an oxide, a boride and a nitride; the oxide comprises one or more of Al2O3, ZrO2, SiO2, TiO2, ThO2, B2O3 and MgO; the boride comprises one or more of TiB2, ZrB2, CrB2 and MgB2; and the nitride comprises one or more of AlN or TiN. Compared with a traditional copper-based material of which the strength is enhanced and the conductivity is ignored, the strength of the carbon nanotube / bronze copper-based material is kept to be increased by adding the carbon nanotubes into bronze, and the conductivity of the carbon nanotube / bronze copper-based material is improved by adding the nanoscale particle reinforced phases into the bronze, so that excellent properties of high-strength and high-conductivity of the copper-based material are realized.

Description

technical field [0001] The invention relates to the technical field of copper-based materials, in particular to a high-strength and high-conductivity copper-based material and a preparation method thereof. Background technique [0002] Copper and copper alloys have broad application prospects in the fields of automobiles, aerospace and electronics because of their good electrical and thermal conductivity and processing properties. [0003] However, due to the low strength of copper and copper alloys, they are prone to breakage during use. In the prior art, while increasing the strength of copper-based materials through deformation or solution-aging, the problem of electrical conductivity decline is often ignored. Therefore, the present invention provides a high-strength and high-conductivity copper-based material and a preparation method thereof to obtain a copper-based material with good strength and electrical conductivity. Contents of the invention [0004] In order to...
